    Vizio VF550M 55" LCD - PS cap values please anyone?

    Hi folks.

    Does anyone know what caps are used in the power supply for these? Per search indication there is no known schematic for these.

    Since this is my only TV I am hoping to do my repairs in one shot without missing any of my favorite shows so I would like to have parts on hand rather than pull unit, check then wait for parts order.

    These are probably common values even suggestions of what to stock up on would be better than nothing.

    Also anyone have insight maybe into something I read on a similar unit that stated "replace all caps except the big one." I take it this would be noted just because it's only really small caps that fail/leak/bulge?

    Thanks!!!

    I use PANASONIC FM/FC/FR for all my repair, just look at the value and the dimension of the caps, since PS can be more than one revision so you have to get to the board to see exactly what you have.
    There is more than one revision of the TV also:

      Thanks. Thing is where I am I will have to order/have shipped so there would be a gap between removing and servicing where I would be in TV withdrawal. That's why I'd like get the caps first. Even if I have to buy extras values based on uncertainty that would be fine. So if anyone knows these that would be great.

      thx!

        That will be tough because you do not know which power supply is being used in that TV.
        Typical values are:
        Cold side
        1000uF 10V
        1200uF 10V
        2200uF 10V
        470uF 10V
        680uF 10V

        470uF 25V
        680uF 25V
        1000uF 25V
        1200uF 25V

        470uF 35V
        680uF 35V
        1000uF 35V
        1200uF 35V

        Hot side:
        22uF 50V
        33uF 50v
        47uF 50v
        56uF 50V

          I will change out the large cap (the big one), only because of the age of your TV.
